"Bad choice bro..." Lewis refused to compliment such a disgusting gas machine that never stopped, and now it was time for his usual punishment for disobeying you. You decide to start with something simple, you rip a massive blast on your brother's face, making him squirm and cry for help. You blast another one in Lewis, this time, the smell almost stank up the whole room. You can feel you poor little brother struggle under your butt, it clear that he had regretted his choice, and wanted to compliment your rear, but it was too late now.
You feel a last cloud of gas coming down your stomach, but this wasn't any ordinary fart, you could feel this was an special one, and you wanted Lewis to feel it too. You push the poor kids face even deeper in you butt, and as the blast was coming, you warned Lewis "Better be careful with this one, it really feels toxic!" Before you could even finish the sentence, the fart was already coming out, it lasted 12 seconds, and the smell was unbearable, even for you, you couldn't even imagine how Lewis was experiencing the smell of that one. At first, he struggled harder than ever, however, it wasn't enough to get you off him, but then, he suddenly stopped, at first, you thought that your stinky ass had killed him, but that was almost impossible. You stood up and looked at your brother, he looked pretty weak, but not unconscious, he was probably about to pass out, but somehow, he was still awake and aware of what was happening.
It was time to continue his punishment, it wasn't over, it was only the begining.
